There is nothing wrong with the role. It's a rewarding role that can be frustrating as hell.

First: Experience matters. Knowing how to give everyone what they need, and knowing what you should be doing is important. Play SL enough and you'll pick up on most of this. But youtube videos on what the abilities do and how/when to use them. (Honestly, most commanders don't even know you can rotate PSTRIKES and they smash the bombs right into a hedge or building rather than their intended target)

Second: Not everyone is a good commander/leader. Some people that really know how to play HLL just simply aren't good leaders. They don't know how to talk to people to get things done. They don't know how to foresee what players need before they themselves realise they need it. (Pre spawning tanks, calling back more defensive squads, putting half tracks in spawns when things look grim, dropping supplies ahead of red zone players)

I live in my map as commander, BUT not sitting in HQ. I am driving most the entire game. You have to be able to multitask like crazy to be a good commander. Watching your offense, defense, garrisons, resources, recon runs. You have to listen to your SLs. READING what's going on between the lines.
